    The Dr. is stressful and difficult for me to talk to. He doesn't so much talk to me, he talks about me to his digital recorder. So far my appointments have felt really rushed, and I find it difficult to ask questions. He is polite, and I appreciate the care I have received. Unfortunately I would dread needing to have more complex conversations with him. As it is, my very simple medication needs haven't necessitated much and even that has been a bit off putting.

    He treated me like I was disgusting because I smoked cigarettes, and to him, I stank. He started telling the nurse to leave the door open, and when the nurse came back, he said, "Because of this smell, now I'm going to have to open the window." I didn't like that because there are many patients there with different smells, and I worry that he treats them the way he treated me. Thank you very much.

    It was obvious the provider had not reviewed the chart/referral notes before walking into the room. The provider focused almost exclusively on lab timings and values with almost no time spent on my primary complaint and/or the value of resolving it relative to lab values. The provider appeared to assume an extremely high level of knowledge on my part of endocrinology terminology -- the names and types of hormones and their interactions, their sources, their interactions, extrinsic and intrinsic factors that might affect their levels, and how those fluctuating levels might impact my symptoms. [redacted] I do very much appreciate that Dr. Nicasio is attempting to make sure I'm getting appropriate treatment, but I also came away feeling like "appropriate treatment" meant (only) that appropriate testing was done at appropriate intervals, and that any medications was administered and adjusted only on that basis, and not taking much account of my main complaints. Perhaps that's incorrect -- but it's the impression I was left with.

And, it caused me to have to shuffle my plans for the rest of the afternoon. If I arrived 45 minutes late for an appointment I would need to lay and reschedule. I realize he was accommodating another patient who arrived late, but it was unreasonable to make me wait 45 minutes. Time management skills should be improved. It is extremely hard to schedule an endocrinologist appointment but it if this continues I will need to re evaluate, despite the fact that I like Dr. Nicasio very much as a doctor.

    I had a good experience with Dr. Nicasio. I think he's well informed. He knows his endocrinology medicine, and he treated me with respect, and he explained things to me, and that's important.

    John Nicasio is the best endocrinologist my wife and I have seen in nearly 30 years of seeing them. Thorough, curious about seemingly anomolous test results. He's been the first to get her diabetes under control, and the first to identify the cause of my weird test results that other doctors have brushed off for years. Cling to that man. He's a rare gem.

    Dr. Nicasio is an extraordinarily professional. He has come to every appointment familiar with my case and updated information in my record. He listens attentively and explains things clearly. What I appreciate most is the way he dictates detailed information into my record, which allows me to hear this information at the same time. Because I have this information, I am able to ask Dr. Nicasio specific questions about the information. It has been a privilege and a blessing to work with him.
